Abstract

本实用新型涉及一种滑块捞矛,属于石油勘探开发油水气井修井打捞作业工具技术领域,由上接头、捞矛杆、滑块卡瓦、引鞋组成,上接头为偏心接头,其下端与捞矛杆螺纹连接;捞矛杆下端的引鞋为笔尖状。在打捞多级并排紧贴套管壁的落物时,由于偏心接头和笔尖状引鞋的作用,偏心滑块捞矛的下端紧贴套管壁,可以顺利地进入鱼腔,实现捞获落物的目的,复杂情况下进行简单的换向操作即可。

Description

一种滑块捞矛
技术领域:
本实用新型涉及一种滑块捞矛,属于石油勘探开发油水气井修井打捞作业工具技术领域。
背景技术:
在油气田修井、作业施工中,由于人为操作、油层套管的内径尺寸、井内油管的尺寸及材质的因素的影响,往往会形成多级管类落物同时并排处于同一井段的现象。现有的打捞工具由上接头、捞矛杆、滑块卡瓦、引鞋组成,上接头与捞矛杆处于同心位置,当多级并排落物的鱼顶紧贴套管壁时,即使采取多次换向操作,捞矛杆也无法进入鱼腔,致使打捞失败。
发明内容:
本实用新型的目的是为了克服现有技术无法实现紧贴套管壁的多级并排管类落物打捞的缺陷,提供一种偏心式滑块捞矛。
本实用新型由上接头、捞矛杆、滑块卡瓦、引鞋组成,上接头为偏心接头,其下端与捞矛杆螺纹连接。
捞矛杆下端的引鞋为笔尖状。
本实用新型的有益效果是:在打捞多级并排紧贴套管壁的落物时,由于偏心接头和笔尖状引鞋的作用,偏心滑块捞矛的下端紧贴套管壁,可以顺利地进入鱼腔,实现捞获落物的目的,复杂情况下进行简单的换向操作即可。
附图说明:
图1为本实用新型实施例的剖视图。
具体实施方式:
本实用新型由上接头1、捞矛杆2、滑块卡瓦3、引鞋4组成,上接头1为偏心接头,其下端与捞矛杆2螺纹连接;捞矛杆2下端的引鞋4为笔尖状。
在修井打捞施工时,将本实用新型与下井钻具连接,由于偏心接头1和笔尖状引鞋4的作用,捞矛杆2可紧贴套管壁,使捞矛杆2顺利地进入紧贴套管壁的鱼腔,从而实现捞获井下落物的目的。 

Claims (2)
